I will be staying at a B&B at 4th Ave & Arbutus St for 8 days, need to get to Granville Island by 6:30 each am. I know it will be dark at that time. I am a small but healthy woman. Is it safe to walk alone? I planned to walk east on 4th Ave, then north on Fir St to 2nd Ave then to Lamey's Mill Rd and the Old Bridge Walk into the island.
